GASOLI N E-STOVE.

SPECIFICATION forming part of Letters Patent No. 401,016, dated April 9, 1889.

Application iled December 17, 1888. Serial No. 293,893. (No model.)

T0 all whom it may concern:

Be it known that I, WILLIAM PEYroN DUN- HAM, of Belleville, in the county of Republic a'nd State of Kansas, have invented a new and useful Improvement in Gasoline-Stoves, of whichthe following is a specification.

My invention is an improvement in what are generally known as gasoline-stoves g and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a sectional View of a part of a stove with my improvements applied. Fig. 2 is a perspective view of my improvements. Fig. 3 is a detail view showing the connection-piece in section. Fig. 4 is a detail top plan view of the connectionpiece, and Fig. 5 shows a somewhat different construction of connection-piece.

The shaft A is the valve-shaft or shank of a gasoline-stove, and may, except in the particulars hereinafter described, be of any suitable construction. Near its lower end this shaft A has a downwardly-facing shoulder, B, below which the shaft has a hexagonal or other non-circular portion, C, while below such portion C, I provide a screw tenon or portion, D, on the shaft. Through the shaft A, preferably immediately below the shoulder B, I form a transverse opening, b, for the passage of the pin E, presently described. The lever F unites at its inner end with a connection-piece, G, usually and preferably by fitting the inner end of the lever-arm in al socket, g, in said piece G, which socket may be threaded or not, as desired; but it is preferably threaded, to facilitate the joining of the lever-arm and the connection-piece. This connection-piece has an opening, H, formed through it, which opening is fitted to receive the non-circular portion C of the shaft A. In the upper face of piece G, I form grooves I, which may be brought into register with the opening b and receive the pin E when the latter is inserted through opening b.

It will be seen that the connection-piece may be adj usted to different positions on the shaft, to set the lever-arm. at different radial positions, by removing such connection-piece from the shaft, turning the said piece as destruction is found in practice to be a greatimprovement over the ordinary construction, in which the lever is formed with a circular oriiice receiving the circular shaft and clamped by a screw turned through the lever and bearing against the shaft, the said screw being sometimes stripped of its thread and at other times slipping and cutting grooves e or furrows in the valve-shaft, and being` otherwise objectionable, as will be understood.

By my improved construction, as shown, the connection-piece when properly applied and secured cannot slip, being' prevented from so doing by the non-circular opening and portion and by the pin E. Near its outer end the lever extends adjacent a toothed bar or rack, K, suitably supported in the framing of the stove; and on the shaft, in position to engage the said rack, I pivot above shoulder 'L' the pawl L, having its free edge Z adapted to engage the rack K, and provided with a handle-like portion, l', arranged near to the handle end of the lever, so it may be engaged by the fingers of the operator when it is desired to release the pawl from the rack in order to adjust the lever to different positions. It will be seen that this construction is simple, effective, and can be easily operated.

In Fig. 5 the connection-piece is shown formed with ahinged socket-section, so the angle of the lever-arm may be varied, if desired.

Having thus described my invention, what I claim as new is- 1. A gasoline-stove valve-shaft formed with a portion, C, and an opening, b, combined with the lever-connecting piece having an opening fitted to receive portion C, and provided in its face with a groove or grooves registering with opening b, and the pin E, fitting in said grooves and opening, substantially as set forth.

2. In a gasoline-stove, the combination of the rack K, the valve-shaft, the lever whereby to turn said shaft, and the pawl pivoted on the lever arranged to engage the rack, and having a handle-like portion extended adja- IOO eent to the handle of the lever, substantially as set forth.

3. The improvement in gasoline -stoves herein described, consisting of the valve-shaft having' Shoulder B, opening b, non-circular portion C, and threaded part D, the connection-piece G, having socket g, opening` H, and grooves I, and having opening I-I formed to receive portion C of the shaft, the nut-secur- 1o ing piece G on suoli portion, the pin E, fitted in groove I and opening b, the pawl L, pivoted on the 1ever-ar1n near its outer end and having,r a handle portion, Z', and the rack arranged for engagement by said pawl, substantially as set forth.
